This version of the Caliber 13''' NOBRK has presumably no original hands. The hand form is Cathedral.

The glass is of celluloid.

Remarks

The model is also called "NOBRK". There is a lady's pocket watch, which is touted by 1927 as "Miss" in the Junghans catalog. In the same catalog the wrist watches (called in the catalog "Bracelets lever escapement watches") enumerated after their case form: Rond, Carré, Carré illusion and Octogon

All forms were each plated (polished) or gilded. Further examples of the Junghans J53 that was installed by the company Ingersoll:
